JELEECTRC-LIEGHTING FJIE'QULURE.

Application led March 9, 1922. Serial No. 542,435.

To all whom it may concern:

l Be it known that lEnwAnn Lewis DALES, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, has invented certain new and useful Improvements in Flectric-Lighting Fixtures, of which the following is a specification.

My invention relates to electric lighting fixtures. i

The principal object of the invention is to provide a fixture of the class stated wherein two reectors are utilized, viz r-a horizon-.

tal reflector at-the top of the fixture and a reflector surrounding the lamp, constituting; a two piece electric lighting unit, this unit eing associated with a combined socket cover and support for the lower reflector, the support being capable of vertical adjustment to secure the proper distribution of light.

A further object of the invention is to provide a cup shaped reflector to be placed over the lower end of the lamp to serve as an additional light shield, when required.

A still further object of the invention is to provide a xture of the class described wherein the diameter and contour of the horizontal reHector at the top thereof, combined with the diameter and height of the lower reflector are so proportioned as to secure a graded distribution of light without definite shadow. Y

. Other objects and uses of the invention will appear from a detailed description of the same, which consists in the features of construction and combinations of parts hereinafter described and claimed.

lln the accompanying` drawings forming a part of this'specilication, and inl which similar reference characters indicate like parts in each of the views Figure 1 is a side elevational view, partially in section, of a two piece lighting unit, embodying my invention;

F igure 2 is an inverted plan view thereof.

Referring in detail to the drawing, the fixture, as an entirety, is designated by the character A, and comprises a horizontal reflector a, shown in the drawing mounted on a tripod B, adapted to be connected to the electric outlet in the ceiling, or where an outlet box (not shown) is provided on the ceiling` then such tripod B may be connected therewith by' any suitable means, such, for instance, as a nipple and whatever additional parts, i. e., joint, hickey, etc., that may/'be required Aby the conditions of the electric outlet. 'lhere should, however, be no appreciable space between said reflector a and the ceiling, in order that no halations or shadows may be cast thereon by said re- Hector.

A threaded nipple C provided in the base of the tripod B is designed for engagement with one end of a short pipe D, the lower end whereof passes through an opening in the upper lportion of a metal socket cover F and has a threaded engagement with a standard` commercial lamp socket F. into which is adapted lto be threaded an electric lamp or bulb H having a threaded upper portion Gr thereto for such purpose. rlhe socket lll is wired for electrical current in accordance with the requirements of lthe electric outlet in the ceiling.

'lhe horizontal redector a also serves as a canopy to cover the electric outlet.

The socket cover F is adapted to act as a support for the horinontal redector a., and the lower reflector M is suspended therefrom by means of supports l, shown in the drawing as three, but they may be of whatever number required for the purpose; the lower portions Jl of said supports lf being threaded and secured in brakets l provided on the upper portion ofsaid reflector M by means of nuts lL, whereby vertical adjustment may be made of said reflector M which surrounds the lamp ll. 'lhe means for suspending said lower reflector M from the socket cover F, however, maybe varied without departing from the salient features of my invention.

rllhe horizontal reflector or canopy a is constructed with the convex portion- A on its outer surface, to reflect the light rays cast thereagainst and it may be constructed either of metal orglass. When made of glass, with the surface broken up by sand blasting or other means to produce a light did'using surface, the inner surface may be colored and decorated and the outer surface oiled, resulting in an unique and pleasing effect both in appearance and lighting values.

l prefer to fashion the convex portion A", of the reflector a, in the form shown, namely,

ltltl that said portion IA shall have a' greater diameter than'thdlargest diameter of the lower reflector M, whereby the beams of light from thelamp l-l will, uponstriking the curved surfaces thereof,.be widely radiilluminate the outside surface 'of the lower reflector M.

When it is desired to further shield the eyes of the beholder from the direct light rays from the lamp H, lamps of the type of vMazda C4, with frosted or enameled tip may be used. 'Io completely shield the eyes from the' direct rays from said lamp H, a sheet metal cup N, conforming to the contour of the larger and lower end of the lamp H is positioned thereover. This cup N is supported in plac by three or more wire clips P. An opening O in the base of said cup N permits the passage lof the pointed end H provided on the usual commercial type of lamp.l I

One of the wired clips P is in turn wiredby a wire Q, to one of the supports I of the lower reflector M, so that the cup may be removed from the lamp, for the removal or replacement of said lamp or to clean the fixture, or other purpose, without removing said cup N entirely from the fixture.

The inside of the cup -N is to be provided with an efficient reflecting surface. The outside thereof to be colored as required by the.

finish of the fixture. By the use of this cup N the fixture partakes of anindirect lighting type, while without its use the fixture is more or less a semi-indirect lighting type.

Iny the foregoing detailed description I have disclosed an electriclighting fixture having severalA features of novelty and utility, such as, a lighting fixture comprising a horizontal reflector which acts as a canopy; the use of glass for this horizontal reflector-Witt a) diffusing surface and col- A ored or otherwise decorated, mainly on the insideand oiled on the outside; a Vertical metal reflector in connection with said horizontal reflector, dimensioned to produce a graded illumination without shadow, receiv` ing reflected light on its outside surface from the horizontal reflector and arranged for yvertical adjustment; a means for` entirely concealing the direct light rays of the lamp by using a third reflector over the tip of the lamp; a fixture,` simple and economical in construction which because of the arrangements and proportions of its parts is pleasing en masse; a fixture which will not and therefore lend itself for use in any surroundings, i. e., commercial use, where illuminating efficiency is` the main consideration, or as part of the decoration of an artistic interior.

Obviously minor modifications, not involving invention, may be made in the construction of the fixture without departing from the spirit of my invention or the scope of the appendedy claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is l. An electric light fixture, comprising in combination, a horizontal reflector convex on its outer surface, a lamp socket, a -lamp secured in said socket, a socket cover supporting said reflector and a reflector suspended from said socket cover and surrounding said lamp, said horizontal reflector be-` ing made of glass with its outer surface broken up to produce a light diffusing surface and the inner surface thereof being decorated, substantially as described.

2. An electric light fixture, comprising in combination, a horizontal reflector convex on its outer surface, a lamp socket, a lamp secured in said socket, a socket cover supporting said reflector, a reflector suspended from said socket cover and surrounding said lamp, a cup conforming to the contour ofthe lower and'larger portion of said lamp and adapted to fit t'hereover and means to retain said cup in position on said lamp to divert the direct rays from said lamp, substantially as described.

3. An electric light fixture, comprising in combination, a horizontal reflector convex on its outer surface, a lamp socket, a lamp secured in said socket, a socket cover supporting said reflector, a reflector suspended from said socket cover and surrounding said lamp, a cup conforming to the contour of the outer lower portion of said lamp and adapted to fit thereover, clips to retain Said cup in position on said lamp and means to secure one of said clips to the "suspending means from said socket cover to said lower reflector, substantially as described.

In testimon whereof I affix my signature.
